Today we will look at the form वैनतेयात् m-Ab-s from रघुवंशम् 16.88.

इत्थं नागस्त्रिभुवनगुरोरौरसं मैथिलेयं लब्ध्वा बन्धुं तमपि च कुशः पञ्चमं तक्षकस्य ।
एकः शङ्कां पितृवधरिपोरत्यजद्वैनतेयाच्छान्तव्यालामवनिमपरः पौरकान्तः शशास ॥ 16-88॥

टीका –
इत्थं नागः कुमुदः । त्रिभुवनगुरोः त्रयाणां भुवनानां समाहारस्त्रिभुवनम् । ‘2-1-51 तद्धितार्थ-‘ इत्यादिना तत्पुरुषः । अदन्तद्विगुत्वेऽपि पात्राद्यदन्ततत्वान्नपुंसकत्वम्। ‘पात्राद्यदन्तैरेकार्थो द्विगुर्लक्ष्यानुसारतः’ इत्यमरः । तस्य गुरू रामः । तस्य औरसं धर्मपत्नीजं पुत्रम् । ‘औरसो धर्मपत्नीजः’ इति याज्ञवल्क्यः । मैथिलेयं कुशं बन्धुं लब्ध्वा । कुशोऽपि च तक्षकस्य पञ्चमं पुत्रं तं कुमुदं बन्धुं लब्ध्वा एकः तयोरन्यतरः कुमुदः [पितृवधरिपोः] पितृवधेन रिपोः वैनतेयात् गरुडात् । गुरुणा वैष्णवांशेन कुशेन त्याजितक्रौर्यादिति भावः । शङ्कां भयम् अत्यजत् । अपरः कुशः शान्तव्यालां कुमुदाज्ञया वीतसर्पभयाम् अवनिम् अत एव पौरकान्तः पौरप्रियः सन् शशास ।। ८८ ।।

Translation – Thus the serpent (Kumuda), having obtained Kuśa – a legitimate son of Rāma (the master of (the collection of) the three worlds) and Sītā (the princess of Mithilā) – as a relative, abandoned fear from the enemy Garuḍa (son of Vinatā) who had slain his father. And in turn Kuśa, loved by his subjects, having obtained Kumuda – the fifth son of Takṣaka – as a relative , ruled the earth freed from the fear of serpents (88).

The above verses have previously appeared in the following post – त्रिभुवनगुरोः mGs

विनताया अपत्यम् (पुमान्) = वैनतेयः (गरुडः) – a (male) descendant of Vinatā. It refers to Garuḍa (son of Vinatā)
In the verses the विवक्षा is पञ्चमी-एकवचनम्। Hence the form is वैनतेयात्।

(1) विनता ङस् + ढक् । By 4-1-120 स्त्रीभ्यो ढक् – To denote the sense of अपत्यम् (descendent), the तद्धित: affix ‘ढक्’ may be applied optionally following a syntactically related पदम् in which the सन्धिः operations have been performed, provided the पदम् ends in a sixth case affix and has a base ending in a feminine affix (prescribed in the अधिकारः of 4-1-3 स्त्रियाम्)।
Note: As per the प्ररिभाषा ’प्रत्ययग्रहणे तदन्तग्रहणम्’ – The term ‘स्त्रीभ्यः’ should be understood as ’स्त्रीप्रत्ययान्तेभ्यः’, that is terms ending in the feminine affixes like टाप्, ङीप् etc.
Note: The सूत्रम् 4-1-120 स्त्रीभ्यो ढक् applies in the present example, since the प्रातिपदिकम् ’विनता’ ends in the feminine affix ‘टाप्’।
As per the सूत्रम् 4-1-92 तस्यापत्यम् – Following a syntactically related पदम् in which the सन्धिः operations have been performed and which ends in a sixth case affix the तद्धिता: affixes already prescribed (by the prior rules 4-1-83 प्राग्दीव्यतोऽण् etc), as well as those that are going to be prescribed (by the following rules 4-1-95 अत इञ् etc), may be optionally applied to denote the sense of अपत्यम् (descendant.)

(2) विनता ङस् + ढ । अनुबन्ध-लोपः by 1-3-3 हलन्त्यम्, 1-3-9 तस्य लोपः। Note: The fact that the सूत्रम् 7-1-2 आयनेयीनीयियः फढखछघां प्रत्ययादीनाम्‌ (used in step 4) specifically prescribes the substitution ‘एय्’ in place of the letter ‘ढ्’ occurring in the beginning of an affix, obviously implies that the letter ‘ढ्’ in the beginning of an affix (such as ढक्) does not get the इत्-सञ्ज्ञा by 1-3-7 चुटू‌। Because, otherwise the letter ‘ढ्’ would be elided by 1-3-9 तस्य लोपः।

Note: ‘विनता ङस् + ढ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 सुपो धातुप्रातिपदिकयोः to apply in the next step.

(3) विनता + ढ । By 2-4-71 सुपो धातुप्रातिपदिकयोः – A सुँप् affix takes a लुक् elision when it is a part of a धातुः or a प्रातिपदिकम्।

(4) विनता + एय् अ । By 7-1-2 आयनेयीनीयियः फढखछघां प्रत्ययादीनाम्‌ – The letters ‘फ्’, ‘ढ्’, ‘ख्’, ‘छ्’ and ‘घ्’ – when they occur at the beginning of a प्रत्यय: (affix) – are replaced respectively by ‘आयन्’, ‘एय्’, ‘ईन्’, ‘ईय्’ and ‘इय्’।
Note: As per the सूत्रम् 1-3-10 यथासंख्यमनुदेशः समानाम्, the substitutions take place respectively.

Note: The affix ढक् is a कित् (has the letter ‘क्’ as a इत्) and this allows 7-2-118 to apply in the next step.

(5) वैनता + एय । By 7-2-118 किति च – The first vowel among the vowels of a अङ्गम् which is followed by a तद्धित: affix (ref. 4-1-76 तद्धिताः) which is a कित् (has the letter ‘क्’ as a इत्) takes the वृद्धि: (ref. 1-1-1 वृद्धिरादैच्) substitute.

Note: The अङ्गम् ‘वैनता’ gets the भ-सञ्ज्ञा by 1-4-18 यचि भम् which allows 6-4-148 यस्येति च to apply in the next step.

(6) वैनत् + एय । By 6-4-148 यस्येति च – When the letter ‘ई’ or a ‘तद्धित’ affix follows, the (ending) इ-वर्ण: (letter ‘इ’ or ‘ई’) or the (ending) अवर्ण: (letter ‘अ’ or ‘आ’) of the अङ्गम् with the भ-सञ्ज्ञा takes elision (लोपः)।

= वैनतेय । The प्रातिपदिकम् ‘वैनतेय’ declines like राम-शब्दः।

(7) वैनतेय + ङसिँ । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्‌।

(8) वैनतेय + आत् । By 7-1-12 टाङसिङसामिनात्स्याः, 1-1-55 अनेकाल्शित्सर्वस्य। Note: 1-3-4 न विभक्तौ तुस्माः prevents the ending letter ‘त्’ of ‘आत्’ from getting the इत्-सञ्ज्ञा।

(9) वैनतेयात् । By 6-1-101 अकः सवर्णे दीर्घः।

We can similarly derive the following –
१) कुन्त्या अपत्यम् (पुमान्) = कौन्तेयः (अर्जुनः) – a (male) descendant of Kuntī. It generally refers to Arjuna (son of Kuntī).
२) सरमाया अपत्यम् (पुमान्) = सारमेयः – a (male) descendant of Saramā. Saramā is the name of the female dog belonging to the gods. Hence Sārameya refers to a dog.
३) द्रौपद्या अपत्यम् (पुमान्) = द्रौपदेयः – a (male) descendant of Draupadī.

Today we will look at the form वासुदेवम् mAs from श्रीमद्भागवतम् 4.22.39.

यत्पादपङ्कजपलाशविलासभक्त्या कर्माशयं ग्रथितमुद्ग्रथयन्ति सन्तः ।

श्रीधर-स्वामि-टीका –

GitaPress translation – Resort (then) as your (sole) refuge to Lord Vāsudeva, by fixing the thought on the splendor of the very toes of whose lotus-feet pious souls cut asunder the knot of egotism (which us nothing but a conglomerate of tendencies to action) formed (by Karmas themselves), in a manner that even recluses who have emptied their mind (of all thoughts of the world), having withdrawn their senses (from their objects) are not able to do (39). Great agony is experienced in crossing the ocean of metempsychosis – which is infested with (fierce) crocodiles in the shape of the five senses and the mind – by those who have not found their boat in God, inasmuch as they seek to reach the other end of it by painful means (such as the practice of Yoga.) Therefore, you make the adorable feet of Lord Śrī Hari your boat and cross the ocean of misery, which is so difficult to cross (40).

The above verses have previously appeared in the following post – तितरिषन्ति-3ap-लँट्

वसुदेवस्यापत्यम् (पुमान्) = वासुदेवः – a (male) descendant of the Vasudeva (of the Vṛṣṇi dynasty). Here it refers to Śrī Kṛṣṇa.
In the verses the विवक्षा is द्वितीया-एकवचनम्। Hence the form is वासुदेवम्।

(1) वसुदेव ङस् + अण् । By 4-1-114 ऋष्यन्धकवृष्णिकुरुभ्यश्च – To denote the sense of अपत्यम् (descendant) the तद्धित: affix ‘अण्’ may be applied optionally following a syntactically related पदम् in which the सन्धिः operations have been performed, provided the पदम् ends in a sixth case affix and has as its base the name of a sage, or of one born in the ‘अन्धक’, ‘वृष्णि’ or ‘कुरु’ dynasty.
Note: First the सूत्रम् 4-1-83 प्राग्दीव्यतोऽण् prescribes the default affix ‘अण्’ which is over-ruled by the affix ‘इञ्’ (prescribed by the सूत्रम् 4-1-95 अत इञ्) and finally the सूत्रम् 4-1-114 ऋष्यन्धकवृष्णिकुरुभ्यश्च re-prescribes the affix ‘अण्’ because ‘वसुदेव’ denotes the name of one born in the ‘वृष्णि’ dynasty.
As per the सूत्रम् 4-1-92 तस्यापत्यम् – Following a syntactically related पदम् in which the सन्धिः operations have been performed and which ends in a sixth case affix the तद्धिता: affixes already prescribed (by the prior rules 4-1-83 प्राग्दीव्यतोऽण् etc), as well as those that are going to be prescribed (by the following rules 4-1-95 अत इञ् etc), may be optionally applied to denote the sense of अपत्यम् (descendant.)

(2) वसुदेव ङस् + अ । अनुबन्ध-लोपः by 1-3-3 हलन्त्यम्, 1-3-9 तस्य लोपः।

Note: ‘वसुदेव ङस् + अ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 सुपो धातुप्रातिपदिकयोः to apply in the next step.

(3) वसुदेव + अ । By 2-4-71 सुपो धातुप्रातिपदिकयोः – A सुँप् affix takes a लुक् elision when it is a part of a धातुः or a प्रातिपदिकम्।

Note: The affix ‘अण्’ is a णित् (has the letter ‘ण्’ as इत्)। This allows 7-2-117 तद्धितेष्वचामादेः to apply in the next step.

(4) वासुदेव + अ । By 7-2-117 तद्धितेष्वचामादेः – The first vowel among the vowels of a अङ्गम् which is followed by a तद्धित: affix (ref. 4-1-76 तद्धिताः) which is either a ञित् (has the letter ‘ञ्’ as a इत्) or a णित् (has the letter ‘ण्’ as a इत्) takes the वृद्धि: (ref. 1-1-1 वृद्धिरादैच्) substitute.

Note: The अङ्गम् ‘वासुदेव’ gets the भ-सञ्ज्ञा by 1-4-18 यचि भम् which allows 6-4-148 यस्येति च to apply in the next step.

(5) वासुदेव् + अ । By 6-4-148 यस्येति च – When the letter ‘ई’ or a ‘तद्धित’ affix follows, the (ending) इ-वर्ण: (letter ‘इ’ or ‘ई’) or the (ending) अवर्ण: (letter ‘अ’ or ‘आ’) of the अङ्गम् with the भ-सञ्ज्ञा takes elision (लोपः)।

= वासुदेव । The प्रातिपदिकम् ‘वासुदेव’ declines like राम-शब्दः।

(6) वासुदेव + अम् । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्‌।
Note: 1-3-4 न विभक्तौ तुस्माः prevents the ending letter ‘म्’ of the affix ‘अम्’ from getting इत्-सञ्ज्ञा।

(7) वासुदेवम् । By 6-1-107 अमि पूर्वः – In place of a preceding अक् letter and the following vowel (अच्) belonging to the affix ‘अम्’ there is a single substitute of that preceding अक् letter.

We can similarly derive the following –
१) धृतराष्ट्रस्यापत्यम् (पुमान्) = धार्तराष्ट्रः – a (male) descendant of (the king) Dhṛtarāṣṭra (of the Kuru dynasty)

Today we will look at the form वासिष्ठाः mNp from श्रीमद्-वाल्मीकि-रामायणम् 1.57.14.

अशक्यमिति चाप्युक्तो वसिष्ठेन महात्मना । प्रत्याख्यातो वसिष्ठेन स ययौ दक्षिणां दिशम् ∥ १-५७-१३ ∥

त्रिशङ्कुस्तु महातेजाः शतं परमभास्वरम् । वसिष्ठपुत्रान् ददृशे तप्यमानान् मनस्विनः ∥ १-५७-१५ ∥

Gita Press translation – “He was, however, told by the mighty Vasiṣṭha that it was not possible to conduct such a sacrifice. Repulsed by Vasiṣṭha, he proceeded to the southern quarter (13). For the accomplishment of the said purpose the king then sought Vasiṣṭha’s sons at the place where they were actually leading an austere life, engaged as they were in a prolonged course of austerities (14). The exceptionally glorious Triśaṅku beheld (from a distance) the hundred high-minded and supremely resplendant sons of Vasiṣṭha practicing austerities (15).

वसिष्ठस्यापत्यम् (पुमान्) = वासिष्ठः – a (male) descendant of the sage Vasiṣṭha. Here it refers to the son of Vasiṣṭha.
In the verses the विवक्षा is प्रथमा-बहुवचनम्। Hence the form is वासिष्ठाः।

(1) वसिष्ठ ङस् + अण् । By 4-1-114 ऋष्यन्धकवृष्णिकुरुभ्यश्च – To denote the sense of अपत्यम् (descendant) the तद्धित: affix ‘अण्’ may be applied optionally following a syntactically related पदम् in which the सन्धिः operations have been performed, provided the पदम् ends in a sixth case affix and has as its base the name of a sage, or of one born in the ‘अन्धक’, ‘वृष्णि’ or ‘कुरु’ dynasty.
Note: First the सूत्रम् 4-1-83 प्राग्दीव्यतोऽण् prescribes the default affix ‘अण्’ which is over-ruled by the affix ‘इञ्’ (prescribed by the सूत्रम् 4-1-95 अत इञ्) and finally the सूत्रम् 4-1-114 ऋष्यन्धकवृष्णिकुरुभ्यश्च re-prescribes the affix ‘अण्’ because ‘वसिष्ठ’ denotes the name of a sage.
As per the सूत्रम् 4-1-92 तस्यापत्यम् – Following a syntactically related पदम् in which the सन्धिः operations have been performed and which ends in a sixth case affix the तद्धिता: affixes already prescribed (by the prior rules 4-1-83 प्राग्दीव्यतोऽण् etc), as well as those that are going to be prescribed (by the following rules 4-1-95 अत इञ् etc), may be optionally applied to denote the sense of अपत्यम् (descendant.)

Note: ‘वसिष्ठ ङस् + अ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 सुपो धातुप्रातिपदिकयोः to apply in the next step.

(3) वसिष्ठ + अ । By 2-4-71 सुपो धातुप्रातिपदिकयोः – A सुँप् affix takes a लुक् elision when it is a part of a धातुः or a प्रातिपदिकम्।

(4) वासिष्ठ + अ । By 7-2-117 तद्धितेष्वचामादेः – The first vowel among the vowels of a अङ्गम् which is followed by a तद्धित: affix (ref. 4-1-76 तद्धिताः) which is either a ञित् (has the letter ‘ञ्’ as a इत्) or a णित् (has the letter ‘ण्’ as a इत्) takes the वृद्धि: (ref. 1-1-1 वृद्धिरादैच्) substitute.

Note: The अङ्गम् ‘वासिष्ठ’ gets the भ-सञ्ज्ञा by 1-4-18 यचि भम् which allows 6-4-148 यस्येति च to apply in the next step.

(5) वासिष्ठ् + अ । By 6-4-148 यस्येति च – When the letter ‘ई’ or a ‘तद्धित’ affix follows, the (ending) इ-वर्ण: (letter ‘इ’ or ‘ई’) or the (ending) अवर्ण: (letter ‘अ’ or ‘आ’) of the अङ्गम् with the भ-सञ्ज्ञा takes elision (लोपः)।

We can similarly derive the following –
१) विश्वामित्रस्यापत्यम् (पुमान्) = वैश्वामित्रः – a (male) descendant of the sage Viśwāmitra

Today we will look at the forms वैश्रवणम् mAs and रावण mVs from श्रीमद्वाल्मीकि-रामायणम् 3.48.21 and 3.48.22.

एवमुक्ता तु वैदेही क्रुद्धा संरक्तलोचना । अब्रवीत्परुषं वाक्यं रहिते राक्षसाधिपम् ।। ३-४८-२० ।।
कथं वैश्रवणं देवं सर्वभूतनमस्कृतम् । भ्रातरं व्यपदिश्य त्वमशुभं कर्तुमिच्छसि ।। ३-४८-२१ ।।
अवश्यं विनशिष्यन्ति सर्वे रावण राक्षसाः । येषां त्वं कर्कशो राजा दुर्बुद्धिरजितेन्द्रियः ।। ३-४८-२२ ।।

Gita Press translation “Enraged when spoken to as aforesaid, Sītā (a princess of the Videha territory) for her part with blood-red eyes addressed the following harsh words to Rāvaṇa (the suzerain lord of ogres) in that lonely place : – (20) “How after calling god Kubera (son of Viśravā), who is hailed by all gods, your (half-) brother, do you seek to perpetrate a foul deed ? (21) All ogres, O Rāvaṇa, will inevitably perish inasmuch as you – who are (so) hardhearted and evil-minded and have not been able to subdue your senses – are their ruler.(22)”

The above verses have previously appeared in the following post – विनशिष्यन्ति-3ap-लृँट्

विश्रवसोऽपत्यम् (पुमान्) = वैश्रवणः, रावणः – a (male) descendant of Viśravā. Note: वैश्रवणः can refer to either Kubera or Rāvaṇa, since both were sons of Viśravā. Here in the verses वैश्रवणः refers to Kubera.
In the verses, the विवक्षा for वैश्रवणम् is द्वितीया-एकवचनम्। And the विवक्षा for रावण is सम्बुद्धिः।

(1) विश्रवण/रवण ङस् + अण् । By 4-1-112 शिवादिभ्योऽण् – To denote the sense of अपत्यम् (descendant) the तद्धित: affix ‘अण्’ may be applied optionally following a syntactically related पदम् in which the सन्धिः operations have been performed, provided the पदम् ends in a sixth case affix and has ‘शिव’ etc (listed in the शिवादि-गण:) as its base.
Note: ‘विश्रवण’ and ‘रवण’ are listed in the शिवादि-गणः, implying that ‘विश्रवस्’ takes the substitution ‘विश्रवण’/’रवण’ when followed by the affix ‘अण्’ in the sense of अपत्यम् (descendant).
Note: First the सूत्रम् 4-1-83 प्राग्दीव्यतोऽण् prescribes the default affix ‘अण्’ which is over-ruled by the affix ‘इञ्’ (prescribed by the सूत्रम् 4-1-95 अत इञ्) and finally the सूत्रम् 4-1-112 शिवादिभ्योऽण् re-prescribes the affix ‘अण्’ because ‘विश्रवण’ and ‘रवण’ are specifically listed in the शिवादि-गण:।
Note: The अनुवृत्तिः of ‘गोत्रे’ from the सूत्रम् 4-1-98 गोत्रे कुञ्जादिभ्यश्च्फञ् does not come into this सूत्रम् 4-1-112. It stops at the prior सूत्रम् 4-1-111 भर्गात्‌ त्रैगर्ते।
As per the सूत्रम् 4-1-92 तस्यापत्यम् – Following a syntactically related पदम् in which the सन्धिः operations have been performed and which ends in a sixth case affix the तद्धिता: affixes already prescribed (by the prior rules 4-1-83 प्राग्दीव्यतोऽण् etc), as well as those that are going to be prescribed (by the following rules 4-1-95 अत इञ् etc), may be optionally applied to denote the sense of अपत्यम् (descendant.)

(4) वैश्रवण/रावण + अ । By 7-2-117 तद्धितेष्वचामादेः – The first vowel among the vowels of a अङ्गम् which is followed by a तद्धित: affix (ref. 4-1-76 तद्धिताः) which is either a ञित् (has the letter ‘ञ्’ as a इत्) or a णित् (has the letter ‘ण्’ as a इत्) takes the वृद्धि: (ref. 1-1-1 वृद्धिरादैच्) substitute.

Note: The अङ्गम् ‘वैश्रवण/रावण’ gets the भ-सञ्ज्ञा by 1-4-18 यचि भम् which allows 6-4-148 यस्येति च to apply in the next step.

(5) वैश्रवण्/रावण् + अ । By 6-4-148 यस्येति च – When the letter ‘ई’ or a ‘तद्धित’ affix follows, the (ending) इ-वर्ण: (letter ‘इ’ or ‘ई’) or the (ending) अवर्ण: (letter ‘अ’ or ‘आ’) of the अङ्गम् with the भ-सञ्ज्ञा takes elision (लोपः)।

= वैश्रवण/रावण । The प्रातिपदिकम् ‘वैश्रवण’ as well as ‘रावण’ declines like राम-शब्दः।

The विवक्षा for वैश्रवणम् is द्वितीया-एकवचनम्।
(6a) वैश्रवण + अम् । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्‌।
Note: 1-3-4 न विभक्तौ तुस्माः prevents the ending letter ‘म्’ of the affix ‘अम्’ from getting इत्-सञ्ज्ञा।

(7a) वैश्रवणम् । By 6-1-107 अमि पूर्वः – In place of a preceding अक् letter and the following vowel (अच्) belonging to the affix ‘अम्’ there is a single substitute of that preceding अक् letter.

And the विवक्षा for रावण is सम्बुद्धिः।
Note: By 2-3-49 एकवचनं सम्बुद्धि: – The nominative singular affix (‘सुँ’) when used in a vocative form gets the designation सम्बुद्धि:।

(6b) (हे) रावण + सुँ । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्‌। By 2-3-47 सम्बोधने च – A first case affix (‘सुँ’, ‘औ’, ‘जस्’) is used to denote ‘address’ (in addition to the meaning of the nominal stem) also. Note: सम् (सम्मुखीकृत्य) बोधनम् (ज्ञापनम्) = सम्बोधनम्। सम्बोधनम् means drawing someone’s attention (to inform him/her of something.)

(7b) (हे) रावण + स् । अनुबन्ध-लोप: by 1-3-2 उपदेशेऽजनुनासिक इत् and 1-3-9 तस्य लोपः।

Today we will look at the form भौमः mNs from श्रीमद्भागवतम् 10.59.21.

शूलं भौमोऽच्युतं हन्तुमाददे वितथोद्यमः । तद्विसर्गात्पूर्वमेव नरकस्य शिरो हरिः । अपाहरद्गजस्थस्य चक्रेण क्षुरनेमिना ।। १०-५९-२१ ।।
सकुण्डलं चारुकिरीटभूषणं बभौ पृथिव्यां पतितं समुज्ज्वलत् । हाहेति साध्वित्यृषयः सुरेश्वरा माल्यैर्मुकुन्दं विकिरन्त ईडिरे ।। १०-५९-२२ ।।

श्रीधर-स्वामि-टीका –
गरुडे वितथोद्यमः सन् शूलं त्रिशूलमाददे धृतवान् ।। २१ ।। २२ ।।

Gita Press translation – His attempt having proved futile, Naraka (son of Mother Earth) picked up a pike with intent to strike at Śrī Kṛṣṇa. (But) before he could discharge it, Śrī Kṛṣṇa with his discus (Sudarśana), which was keen-edged as a razor, lopped up the head of Naraka, who rode on an elephant (21). Fallen on the ground, Naraka’s head, which was accompanied with a pair of ear-rings and adorned with a lovely diadem, shone most resplendent. “Oh, what a pity!” cried his people and “Bravo!” exclaimed the seers; while the chiefs of gods extolled Śrī Kṛṣṇa (the Bestower of Liberation,) covering Him with (a shower of) flowers (22).

The above verses have previously appeared in the following post – गजस्थस्य-mgs

भूमेरपत्यम् (पुमान्) = भौमः – a (male) descendant of Mother Earth. Here it refers to Naraka (son of Mother Earth).

(1) भूमि ङस् + अण् । By 4-1-112 शिवादिभ्योऽण् – To denote the sense of अपत्यम् (descendant) the तद्धित: affix ‘अण्’ may be applied optionally following a syntactically related पदम् in which the सन्धिः operations have been performed, provided the पदम् ends in a sixth case affix and has ‘शिव’ etc (listed in the शिवादि-गण:) as its base.
Note: First the सूत्रम् 4-1-83 प्राग्दीव्यतोऽण् prescribes the default affix ‘अण्’ which is over-ruled by the affix ‘ढक्’ (prescribed by the सूत्रम् 4-1-120 स्त्रीभ्यो ढक्) and finally the सूत्रम् 4-1-112 शिवादिभ्योऽण् re-prescribes the affix ‘अण्’ because ‘भूमि’ is specifically listed in the शिवादि-गण:।
Note: The अनुवृत्तिः of ‘गोत्रे’ from the सूत्रम् 4-1-98 गोत्रे कुञ्जादिभ्यश्च्फञ् does not come into this सूत्रम् 4-1-112. It stops at the prior सूत्रम् 4-1-111 भर्गात्‌ त्रैगर्ते।
As per the सूत्रम् 4-1-92 तस्यापत्यम् – Following a syntactically related पदम् in which the सन्धिः operations have been performed and which ends in a sixth case affix the तद्धिता: affixes already prescribed (by the prior rules 4-1-83 प्राग्दीव्यतोऽण् etc), as well as those that are going to be prescribed (by the following rules 4-1-95 अत इञ् etc), may be optionally applied to denote the sense of अपत्यम् (descendant.)

(2) भूमि ङस् + अ । अनुबन्ध-लोपः by 1-3-3 हलन्त्यम्, 1-3-9 तस्य लोपः।

Note: ‘भूमि ङस् + अ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 सुपो धातुप्रातिपदिकयोः to apply in the next step.

= भौम । The प्रातिपदिकम् ‘भौम’ declines like राम-शब्दः।

(6) भौम + सुँ । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिँभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्।

इदानीं राज्यस्यापकर्षं निरूपयितुमुत्कर्षं निगमयति – युधिष्ठिर इति । कुलन्धरं वंशधरम् ∥ १६ ∥

Gita Press translation “Having got back his kingdom and seen the face of a grandson capable of upholding the traditions of the family, Yudhiṣṭhira in his supreme splendor rejoiced with his younger brothers who were as powerful as the guardians of the various worlds (16).”

पुत्रस्यानन्तरापत्यम् (पुमान्) = पौत्रः – an immediate (male) descendant of a son = grandson (son’s son)
In the verses the विवक्षा is द्वितीया-एकवचनम्। Hence the form is पौत्रम्।

As per 4-1-162 अपत्यं पौत्रप्रभृति गोत्रम्‌ – The designation ‘गोत्र’ is assigned to a grandson/granddaughter onward when the intention is to express him/her as a descendant (अपत्यम्)।
Note: Since ‘कुशिक’ is the name of a sage, the affix ‘अञ्’ in the present example denotes the sense of गोत्रापत्यम् (and not अनन्तरापत्यम्।)

(2) कुशिक ङस् + अ । अनुबन्ध-लोपः by 1-3-3 हलन्त्यम्, 1-3-9 तस्य लोपः।

Note: ‘कुशिक ङस् + अ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 सुपो धातुप्रातिपदिकयोः to apply in the next step.

स कदाचित् प्रभातायां शर्वर्यां रघुनन्दनः । प्रययावभिषेकार्थं रम्यां गोदावरीं नदीम् ।। ३-१६-२ ।।
प्रह्वः कलशहस्तस्तु सीतया सह वीर्यवान् । पृष्ठतोऽनुव्रजन्भ्राता सौमित्रिरिदमब्रवीत् ।। ३-१६-३ ।।

नीहारपरुषो लोकः पृथिवी सस्यमालिनी । जलान्यनुपभोग्यानि सुभगो हव्यवाहनः ।। ३-१६-५ ।।

Gita Press translation – Once that delight of the Raghus, at break of day, went to the beautiful Godāvarī river for the sake of a bath (2). Following at the heels of Śrī Rāma with a vessel for water in his hand together with Sītā, his brave brother, the son of Sumitrā, spoke as follows :- (3) “Now has arrived that season which is dear to you, O polite brother, with which the blessed year appears as though ornamented (4). The people feel dry with cold, the earth is rich with crops; the waters are unenjoyable, the fire is agreeable.” (5)

सुमित्राया अपत्यम् (पुमान्) = सौमित्रिः (लक्ष्मणः) – a (male) descendant of Sumitrā. It refers to Lakṣmaṇa (son of Sumitrā)
In the verses the विवक्षा is प्रथमा-एकवचनम्।

(1) सुमित्रा ङस् + इञ् । By 4-1-96 बाह्वादिभ्यश्च – To denote the sense of अपत्यम् (descendant) the तद्धित: affix ‘इञ्’ may be applied optionally following a syntactically related पदम् in which the सन्धिः operations have been performed, provided the पदम् ends in a sixth case affix and has ‘बाहु’ etc (listed in the बाह्वादि-गण:) as its base. As per the सूत्रम् 4-1-92 तस्यापत्यम् – Following a syntactically related पदम् in which the सन्धिः operations have been performed and which ends in a sixth case affix the तद्धिता: affixes already prescribed (by the prior rules 4-1-83 प्राग्दीव्यतोऽण् etc), as well as those that are going to be prescribed (by the following rules 4-1-95 अत इञ् etc), may be optionally applied to denote the sense of अपत्यम् (descendant.)

Note: First the सूत्रम् 4-1-83 प्राग्दीव्यतोऽण् prescribes the default affix ‘अण्’ which is over-ruled by the affix ‘ढक्’ (prescribed by the सूत्रम् 4-1-120 स्त्रीभ्यो ढक्) which in turn is over-ruled by the affix ‘इञ्’ (prescribed by the सूत्रम् 4-1-96 बाह्वादिभ्यश्च) because ‘सुमित्रा’ is specifically listed in the बाह्वादि-गण:।
Note: Since ‘सुमित्रा’ does not end in the letter ‘अ’ the सूत्रम् 4-1-95 अत इञ् cannot apply here.

Note: आकृतिगणोऽयम्। The बाह्वादि-गण: is a आकृतिगणः – which is a class or group of words in which some words are actually mentioned and there is room left to include others which are found undergoing the same operations.

(2) सुमित्रा ङस् + इ । अनुबन्ध-लोपः by 1-3-3 हलन्त्यम्, 1-3-9 तस्य लोपः।

Note: ‘सुमित्रा ङस् + इ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 सुपो धातुप्रातिपदिकयोः to apply in the next step.

(3) सुमित्रा + इ । By 2-4-71 सुपो धातुप्रातिपदिकयोः – A सुँप् affix takes a लुक् elision when it is a part of a धातुः or a प्रातिपदिकम्।

(4) सौमित्रा + इ । By 7-2-117 तद्धितेष्वचामादेः – The first vowel among the vowels of a अङ्गम् which is followed by a तद्धित: affix (ref. 4-1-76 तद्धिताः) which is either a ञित् (has the letter ‘ञ्’ as a इत्) or a णित् (has the letter ‘ण्’ as a इत्) takes the वृद्धि: (ref. 1-1-1 वृद्धिरादैच्) substitute.

Note: The अङ्गम् ‘सौमित्रा’ gets the भ-सञ्ज्ञा by 1-4-18 यचि भम् which allows 6-4-148 यस्येति च to apply in the next step.

(5) सौमित्र् + इ । By 6-4-148 यस्येति च – When the letter ‘ई’ or a ‘तद्धित’ affix follows, the (ending) इ-वर्ण: (letter ‘इ’ or ‘ई’) or the (ending) अवर्ण: (letter ‘अ’ or ‘आ’) of the अङ्गम् with the भ-सञ्ज्ञा takes elision (लोपः)।

= सौमित्रि । The प्रातिपदिकम् ‘सौमित्रि’ declines like हरि-शब्दः।

(6) सौमित्रि + सुँ । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्‌।

(8) सौमित्रिः । रुँत्व-विसर्गौ by 8-2-66 ससजुषो रुः and 8-3-15 खरवसानयोर्विसर्जनीयः।

Similarly, we can derive the following –

५) अर्जुनस्यापत्यम् (पुमान्) = आर्जुनिः – a (male) descendant of Arjuna (of the Kuru dynasty)

Note: In the above examples, first the सूत्रम् 4-1-83 प्राग्दीव्यतोऽण् prescribes the default affix ‘अण्’ which is over-ruled by the affix ‘इञ्’ (prescribed by the सूत्रम् 4-1-95 अत इञ्) which in turn is over-ruled by the affix ‘अण्’ (prescribed by the सूत्रम् 4-1-114 ऋष्यन्धकवृष्णिकुरुभ्यश्च) and finally the सूत्रम् 4-1-96 बाह्वादिभ्यश्च brings back the affix ‘इञ्’ since ‘कृष्ण’, ‘प्रद्युम्न’, ‘सत्यक’, ‘युधिष्ठिर’ and ‘अर्जुन’ are specifically listed in the बाह्वादि-गण:।
